oh...sorry! Im learning the inner of the Amiga and assembler at the same time. Beautiful but hard! :) I tried it in my a1200 060 and vamp a600 but I guess it needs more testing.

The reason for the music problems is simple: you are using P61 in system-kill mode which means there is no auto-detection of the VBR which in turn means the replayer interrupts will not work on any system with relocated VBR. Fix is simple: Just store the VBR at P61_VBR and the problem is gone. :)

As for the intro: Does its job but I expect something more than just a cube next time. :)
